Subject: [PATCH 1/2] drm/i915: fix get digital port issue in intel_audio
Date: Wed,  6 Jan 2016 10:26:41 +0800	[thread overview]
Message-ID: <1452047202-103072-1-git-send-email-libin.yang@linux.intel.com> (raw)

From: Libin Yang <libin.yang@linux.intel.com>

For DP MST, use enc_to_mst(encoder)->primary to get intel_digital_port,
instead of using enc_to_dig_port(encoder).
